Simple contrastive learning
Webbvised visual representation learning. From a perspective on contrastive learning [29] as dictionary look-up, we build a dynamic dictionary with a queue and a moving-averaged encoder. This enables building a large and consistent dic-tionary on-the-fly that facilitates contrastive unsupervised learning. MoCo provides competitive results under the WebbAlternatively to performing the validation on the contrastive learning loss as well, we could also take a simple, small downstream task, and track the performance of the base network on that. However, in this tutorial, we will restrict ourselves to the STL10 dataset where we use the task of image classification on STL10 as our test task.

Simple and effective instantiations of contrastive learning have been developed using Siamese networks [35, 2, 17, 8, 9]. In practice, contrastive learning methods benefit from a large number of negative samples [34, 33, 17, 8].
